let now about...
to now abot this topics look the videos and read all the information and the last step is make our funny and simple activities!
cell transport!
pasive transport
​Passive transport is the simple exchange of molecules across the plasma membrane, during which the cell does not expend energy, because it favors the concentration gradient or favoring the electric charge gradient, ie, a place where There is a great concentration to one where there is less. The passive cellular process is performed by diffusion
active transport
Active transport requires an energy expenditure to transport the molecule from one side of the membrane to the other, but the active transport is the only one that can transport molecules against a concentration gradient, active transport is limited by the number of transport proteins present
cell division!
The process by which new cells are made is called cell division. Cell division is occurring all the time. Around two trillion cell divisions occur in the average human body every day!
sexual reproduccion
si the cell division that need a male and a female.
asexual reproduccion
si the cell division that need only one cell whitoug other cell.
mitosis and meiosis are a basic step for the cell division, the mitosis divides exactly like the other but the meiosis is divides diferent for reproduccion.
